Using an Iterator
<![CDATA[
The Iterator interface has the following methods:
hasNext.
next.
remove.
Compared to an Enumeration, hasNext() is equivalent to hasMoreElements() and next() equates to nextElement().
import java.util.ArrayList;
import java.util.Collection;
import java.util.Iterator;
public class MainClass {
public static void main(String[] a) {
Collection c = new ArrayList();
c.add("1");
c.add("2");
c.add("3");
Iterator i = c.iterator();
while (i.hasNext()) {
System.out.println(i.next());
}
}
}
